  • the biasing casing 172 is connected to the housing 103. More precisely, the biasing casing 172 is connected to the lower housing portion 102 by two fasteners 178. It is contemplated that the biasing casing 172 could be connected to the housing 103 differently.

  • the regeneration biasing member 174 biases the positioning member 176 toward the projected position. As a result, since the engaging portion 180 engages the engaging surface 162, the regeneration biasing member 174 also biases the regenerative lever 150. More specifically, as the biasing assembly 170 causes the regenerative lever 150 to pivot until the abutting surface 164 abuts the stopper 120, when the positioning member 176 is in the projected position, the regenerative lever 150 is in the initial position.
  • the control assembly 50 is in an initial configuration.
  • the acceleration lever 130 is in the neutral position, and the regenerative lever 150 is in the initial position such that the abutting surface 140 of the acceleration lever 130 abuts the abutting surface 158 of the regenerative lever 150.
  • the acceleration lever 130 is in the neutral position despite being biased toward the regeneration position, because the biasing effect of the regeneration biasing member 174 is greater than the biasing effect of the acceleration biasing member 145.
  • a torque applied by the regeneration biasing member 174 is greater than a torque applied by the acceleration biasing member 145. It is to be noted that the regenerative lever 150 remains in the neutral position despite the biasing forces of the regeneration biasing member 174 because of the stopper 122.
  • the position sensor 144 senses that the acceleration lever 130 is in the neutral position and communicates this to the controller 146.
  • the controller 146 does not control the electric motor 62 to be in either one of a regeneration mode or a motor mode.
  • the control assembly 50 is in an acceleration configuration.
  • a driver of the ATV 20 has moved the acceleration lever 130 so that it is in the acceleration position. It is to be noted that in order to do so, the driver has applied sufficient force to overcome the biasing effect of the acceleration biasing member 145. To reach this configuration, the driver has moved the acceleration lever 130 until the abutting surface 142 abuts the stopper 120. It is to be noted, that in response to the acceleration lever 130 moving from the neutral position to the acceleration position, the regenerative lever 150 remains in the initial position, because of the biasing effect by the biasing assembly 170, and the regenerative lever 150 abutting the stopper 122.
  • the position sensor 144 senses that the acceleration lever 130 is in the acceleration position, and thus that the acceleration lever 130 is in the acceleration mode. This is communicated to the controller 146. In response, the controller 146 controls the electric motor 62 to be in a motor mode for driving the wheels 30 that are operatively connected to the electric motor 62.
  • the driver of the ATV could move the acceleration lever 130 to a position intermediate to the neutral position and the acceleration position. In such a position, the position sensor 144 would also sense that the acceleration lever 130 is in the acceleration mode, and the controller 146 would also control the electric motor 62 to be in the motor mode. However, the torque generated by the electric motor 62 would be less than when the acceleration lever 130 is in the acceleration position.
  • the control assembly 50 is in a brake regeneration configuration.
  • a driver of the ATV 20 has moved the regenerative lever 150 so that it is in the final position. It is to be noted that in order to do so, the driver has applied sufficient force to overcome the biasing effect of the regeneration biasing member 176. To reach this configuration, the driver has moved the regenerative lever 150 until the abutting surface 166 abuts the side 124 of the stopper 122.
  • the acceleration lever 130 moves toward the regeneration position.
  • the acceleration lever 130 moves to the regeneration position, because the regenerative lever 150 no longer pushes on the acceleration lever 130, such that the acceleration biasing member 120 causes the acceleration lever 130 toward the regeneration position.
  • the position sensor 144 senses that the acceleration lever 130 is in the regeneration position, and thus that the acceleration lever 130 is in the brake regeneration mode. This is communicated to the controller 146. In response, the controller 146 controls the electric motor 62 to be in a generator mode. In the generator mode, if the ATV 20 is moving, the electric motor 62 decelerates the ATV 20, and recharges the battery pack 60. In some implementations of the present technology, being that the brake regeneration mode is independent of the braking system of the ATV 20, the life of the braking system can be extended.
  • the driver of the ATV 20 could move the regenerative lever 150 to a position intermediate to the initial position and the maximum position.
  • the acceleration lever 130 would move to a position intermediate to the neutral position and the regeneration position.
  • the position sensor 144 would also sense that acceleration lever 130 is in the regeneration mode, and the controller 146 would also control the electric motor 62 to be in the generator mode.
  • the deceleration would be less than when the acceleration lever 130 is in the regeneration position.
  • the position of the acceleration lever 130 between the neutral and regeneration positions is linearly proportional to the deceleration provided by the ATV 20.
  • the acceleration and regenerative deceleration of the ATV 20 can be controlled by a single sensor.
  • the controller 146 may override the actuation of the acceleration lever 130 or the regenerative lever 150 by the driver in response to some predetermined limitations and/or requirements.
  • an anti-lock system may cause the controller 146 to prevent the electric motor 62 from going in the generator mode when a sensor senses that negative torque causes slipping.
  • the acceleration lever 130 is easily operable by the thumb, and that the regenerative lever 150 is easily operable by the index and/or middle finger
  • an orientation of the housing 103 may be moved about the handrail 46 to which the housing 103 is connected.
  • the orientation of the housing 130 may be moved for a variety of reasons, such as for example, improved ergonomics. In some instances, this movement can be enabled by circular openings defined by the recesses 104, 106.
  • the acceleration lever 130 and the regenerative lever 150 may be operable differently. For example, it may be easier to operate the regenerative lever 150 with the thumb, and to operate the acceleration lever 130 with the index.
  • the controller 146 can also be selectively updated (e.g., via an input) to vary a reading of the position sensor 144 such that the acceleration lever 130 becomes associated with the regenerative braking, and the regenerating lever 150 becomes associated with the acceleration. This modification can be particularly useful when changing an orientation of the housing 103.

Abstract

La présente invention concerne un ensemble de commande pour un véhicule électrique comprenant un logement, des premier et second actionneurs, un capteur de position et des premier et second éléments de sollicitation. Le premier actionneur est mobile entre des première, deuxième et troisième positions, et est sollicité vers la première position par le premier élément de sollicitation. Le second actionneur est mobile entre des quatrième et cinquième positions, et est sollicité vers la quatrième position par le second élément de sollicitation. Dans une configuration initiale, le second élément de sollicitation présente un effet de sollicitation supérieur à celui du premier élément de sollicitation, de telle sorte que les premier et second actionneurs sont, respectivement, dans les deuxième et quatrième positions. En réponse au déplacement du second actionneur vers la cinquième position, le premier actionneur se déplace vers la première position. Le capteur de position communique à un dispositif de commande que le premier actionneur est dans un mode de régénération de frein ou un mode d'accélération sur la base d'une position du premier actionneur.
